Fuel Economy
-
Last Tuesday, EPA administrator Scott Pruitt said the agency does not intend to let California set the agenda for national emission limits on vehicles. He suggested to Bloomberg the EPA plans to cut emission rules aggressively to respond to carmakers' pleas for easing of the corporate average fuel economy rules for 2022 through 2025 that they had agreed to in 2012. Even before Pruitt's latest comments, however, California's attorney general has taken a strong public stance against any such rollbacks.

Electric cars may be all the rage, but for now, all but a tiny fraction of the 250 million vehicles on U.S. roads burn gasoline or diesel fuel. One of the ways that new vehicles are boosting fuel efficiency is the use of what are called "start-stop" systems, which switch off the engine while the car is stopped. Now, as the Department of Energy pointed out Sunday in its Fact of the Week, the number of those systems nearly doubled last year on light trucks sold in the U.S. DON'T MISS: Don't start-stop systems wear out your car's starter?
